Influence of the Pi-Electrons Distribution on the Magnetooptical Activity Stimulation in Some Aromatic Liquids

Experimental results of Faraday rotation spectra in a range between 1.8 – 3.65 eV were obtained for H2O, CCl4, dimethilaniline, benzene, nitrobenzene, o-toluidine, o-anisidine, m-chloraniline and o-chloraniline. Self-consistent field (SCF) semi-empirical quantum mechanics calculations using MNDO/D method for organic molecules was chosen to evaluate electron spectra in visible and UV range to interpret experimental results It is shown that magneto-optical response of samples changes significantly with the geometry of pi-electrons distribution in aromatic liquids.
